Hints:

Each stroke is like a rigid piece of wire with a mass proportional to its length. A closed stroke is just a wire bent into a shape, it has no substance apart from its perimeter.

The ends of a strokes can (and will) join onto other strokes when drawn near enough to another stroke. These joints are pivots so you can use this to build levers, pendulums and other mechanical wonders.

Jointed strokes don't collide with each other. Join both ends to make a rigid structure
